(Submitter supplied) Primary open angle glaucoma (POAG) is a progressive optic neuropathy, which is a major cause of worldwide visual impairment and blindness. Pathological hallmarks of the glaucomatous optic nerve head include retinal ganglion cell axon loss and extracellular matrix (ECM) remodeling of the lamina cribrosa layer. TGF-beta is an important pro-fibrotic modulator of ECM metabolism, whose levels are elevated in human POAG lamina cribrosa tissue compared with non-glaucomatous controls. more...

(Submitter supplied) The mechanical effect of raised intraocular pressure is a recognised stimulus for optic neuropathy in primary open angle glaucoma (POAG). Characteristic extra-cellular matrix (ECM) remodelling accompanies axonal damage in the lamina cribrosa (LC) of the optic nerve head in POAG. Glial cells in the lamina cribrosa may play a role in this process but the precise cellular responses to mechanical forces in this region are unknown. more...

(Submitter supplied) Purpose: Marked extracellular matrix (ECM) remodeling occurs in the human optic nerve head in primary open angle glaucoma (POAG). The glial fibrillary acid protein (GFAP) negative lamina cribrosa cell may play an important role in this remodeling process. The authors report the first study of global and ECM-focused gene transcription differentials between GFAP-negative negative lamina cribrosa (LC) cells from normal and POAG human donors. more...

(Submitter supplied) Gene expression in human optic nerve head (ONH) astrocytes exposed to either 60 mm Hg hydrostatic pressure (HP) or control ambient pressure (CP) was compared using Affymetrix GeneChip microarrays to identify HP-responsive genes. Primary ONH astrocytes from two male Caucasian donors (passage 4) were grown to 75% confluence and were exposed for 6, 24 or 48 h to control ambient pressure (CP6, CP24, CP48) or hydrostatic pressure (HP6, HP24, HP48), or harvested at the beginning of the pressure experiment (CP0). more...

(Submitter supplied) PURPOSE. Triamcinolone acetonide (TA) and dexamethasone (DEX) are corticosteroids commonly used for ocular inflammation but both can cause ocular hypertension. We investigated the differential gene expression profile of human trabecular meshwork (TM) cells in response to treatment by TA compared to that by DEX. METHODS. Total RNA was extracted from cultured human TM cells treated with TA or DEX and used for microarray gene expression analysis. more...

(Submitter supplied) ABSTRACT: Background: Oral Submucous Fibrosis (OSF) is a chronic inflammatory disease resulting in progressive fibrosis of the oral soft tissues. Habit of chewing betel quid has been proposed as an important etiological factor in the development of this disease. But the exact mechanism of pathogenesis is still not clear. Methods: We took microarray approach to identify differentially regulated genes in 10 OSF tissues against 8 pooled normal tissues using oligonucleotide arrays. more...

(Submitter supplied) Since macrophage activation can now be studied at a global level using modern microarray and proteomic analyses, discovery of novel macrophage activation genes is inevitable and important for understanding HIV-associated dementia (HAD). We isolated two different types of primary human macrophages, microglia and monocyte-derived macrophages (MDM) from brain tissue and whole blood respectively. The microarray analysis of differentially regulated macrophage activation genes reported here supports our previous assertions that the mixed glia (MIX) cultured in starvation conditions (DMEM alone) are a non-activated, or “quiescent”, tissue culture model for studying macrophage activation in the brain. more...

(Submitter supplied) COPD is a common and disabling lung disease for which very few therapeutic options are currently available. We reasoned that global gene expression profiling of COPD lungs could reveal previously unidentified disease pathways for potential therapeutic interventions. Forty-eight human lung samples were obtained from lungs or lobes resected for small peripheral lung lesions (5 non-smokers, 21 GOLD 0, 9 GOLD 1, 10 GOLD 2 and 3 GOLD 3 patients). more...

(Submitter supplied) Connective tissue growthfactor (CTGF/CCN2) is a matricellular protein induced by transforming growth factor-beta (TGF-beta) and intimately involved with tissue repair and overexpressed in various fibrotic conditions. We have previously shown that keratinocytes in vitro downregulate TGF-beta induced expression of CTGF in fibroblasts by an interleukin-1 alfa (IL-1alfa) dependent mechanism. With this study we want to get a better overall perspective who fibroblasts respond on TGF-beta and in a TGF-Beta stinulated system, what effect addition of IL-1 alfa have. more...
